Brain atrophy
A recent study from the American Academy of Neurology argues that even within the upper levels of the normal range (approaching 110 mg/dL), blood sugar accounts for 6 to 10 percent of the brain shrinkage in the hippocampus and the amygdala. These two brain structures are part of the limbic system, also known as the emotional brain. They regulate autonomic and endocrine functions and affect associative learning, focus, memory, and fight or flight responses. Shrinkage in these areas leads to depression, mood swings, rage, aggression, Alzheimer's and other dementia and emotional diseases.
